This invention concerns a rotary device for positive fluid action. Idefine such a device as a pump or motor comprising relatively revolvableor rotatable parts. of valve gearing and of enclosures and conduits,which are shaped and interact in such a manner, that the parts mustrelatively rotate or revolve in order to permit a fiuid to pass throughsaid housing. The parts may be relatively uniformly revolved or rotated,whereupon they positively propel a fluid through the housing, and serveas a pump, compressor or booster; or on the other hand the parts shallrelatively predeterminedly revolve or rotate, when a fluid is passedthrough the housing, whereupon the device acts as a motor; or the deviceis adapted both ways.

Rotary devices for positive fluid action are known. But those knowndevices are intricate and complicated, because they require a pluralityof one or theother or of all the revolving or rotating parts, or theyrequire auxiliary gearing in order to revolve or rotate the parts at.predetermined ratios. They are elaborate and cumbersome, because theeffective suction or pressure chambers represent only a small proportionof the whole device. They are inefficient for these reasons and alsobecause there is an excessive friction of parts upon each other.Theydeliver a strongly pulsating flow of fluid during pump action andfluid driven devices of, this character will correspondingly knock andare thus not ordinarily adapted for operation as motors.

These and other disadvantages of the devices of the prior art, as theyappearalso from the following description and from further comparimaticand hydraulic devices are other objectsof the instant invention.

Generally speaking the instant invention relies mechanically upon acouple, and rarely more, intermeshed rotor and valve parts. compactlyand snugly accommodated in a housing, and the features of construction,lubrication and packing arising in connection with gearing converted forthe instant purposes are other objects of the instant invention. r

line and an parts Generally speaking the rotors herein to be describedand having a column concavely flaring out in opposite directions from aslender center portion 95 and carrying a helico-spirally disposed vane33, H3, and H4, or l48,'may bev more readily understood by theexplanation of a mode in which they may be produced The valves, as theyare seen at 2i in Fig. 2 or Fig. 5, at tilt] in Fig. 8 and at l2? inFigs. 10 and 11, are discs with notches 22 spaced regularly around theirperiphery. The notches are for instance shown as sectional clearances,which are blunt at their inner end pointing towards -the axis of thevalve. Let us imagine such a valve as a cutter or hob, which ispredcterminedly spaced relatively to the axis of a rotatable rotorblank, and let the hob be rotated at a predetermined ratio-of speed tothe speed of rotation of the rotor blank, the speed of the rotor blankbeing as many times the speed of the hob as there are notches in'thehob,or,if

there is to be more than one vane convolution per lead of one of thevanes,.then the number of notches divided by the convolutions per lead:

Valve speed (hob):

blank speed (rotor) vane convol./lead Number of notches Thehoborcutter-is-arranged to .cut subs-tan tially in'the plane of the-axis of.the-rotor-blank. If the hoboncutter were not notched, it would ofcourse merely produce a ;concentric concave grooveZfi of circularcross+section upon theirotor blank, which groove may be termed;agtoroidal annular groove. But notches inthe hobor cutter whichcorrespond to the;notches 22in the valve discs 2l leave mateiial-in'thegroove,-which arises in substantially lielico spiral formation. Thusarises, for instance, the vane 39 from ithe bottom '2 of the toroidalannulargroove-"of the rotor of Fig. l. The outer circumference of therotor-23 is shaped to it the body 2-5 of the housing, whichis-essentially a 'hollow;cone,;as shown at; 25, butwhich merges withaficylindrical :27 at one end, as a:pref-erred=form.1of body of thehousing serving to avoid-too zwide an-entrance of the body :ofthe-housing at the large end,-which would :resnlt, if;the-;body-. oiithehous- "with the arrangementzofiFig. 1. lPort 28 may not onlypiercethewalltZ'd of the toroidal Lannular groove below the end .of the vane.33, but-it may extend further Lunderneath the surface of therotoras'indicatedat 32, inorderto have: an adequate cross-section, ordischarge oraintake capacity.

Such a shaft 33 of the motorof Figs. 1 and isshownto be'rivetedat one end upon a ball raceiil-countersunk-intothesmall end of rotor 23. Another ball race 35 isdepressed into the countersinlo29 at the otherend of the rotor, and fitsoverthe shaft'33. Asleeve'et is also slid over thatendof shaft-33.it-engages upon shaft by wayoi across' pin 13! serving to retainthe'ball races, theshaft and the rotor in .theirasscm lcdtposition. s

Ball race 34 accommodates balls 33. Screw 39 indicates a complementarypart of the ball bearing, serving as the other race and for axialadjustment at the small end of the rotor. By way of a set screw thescrew 39 may be set in a preferred position in the housing. Screw 39serves to close the apex of the hollow cone 25 of the housing and foradjusting the rotor in an axial direction, the conical part of the rotor23 being thus set into running but closing proximity with the conicalpart 26 of the body 25 of the housing.

The'other .end of the rotor is supported by a tball bearing comprisingthe aforementioned race sleeve. contributes -:to .a radial i-thrust,acting 'in unison with races 35 .and A2; .The xvoidsLinzthe hand wheel.2413, 44,545 render ;the.=housing open at one end, so thatzthe port128communicates .with .the outside.

11 12Whenithe..motor .of;1 igs.' '11andL-.2is driven by water enteringthrough pipe 64, the rotor will be propelled in counterclockwisedirection as indicated by arrow 65 (Fig. 2), and the valve 2! willrotate in clockwise direction (Fig. 1) as indicated by arrow 66, theoperation being explained in detail hereinafter. The water, the energyof which has been spent, will leave by way of the port 28 of rotor 23,and will splash between the spokes 44 onto an implement which is mountedon the shaft underneath, for instance a sponge 67. The sponge 6'! isassembled upon a rigid core 83 by way of 'which it is mounted upon themotor of Figs. 1 and 2. The core may be suitably perforated, asindicated at St, for the purpose of allowing the water to pass throughsuch core into sponge El.

The sponge E1 or any other implement may be removably mounted .upon' themotor, for instance by way of bayonet lock, groove 79 being indicatedfor such purpose in the hub i l of the core 68, such groove engagingupon the opposite ends of the pin 31 extending from shaft 33 throughsleeve 36. i 1

Water enteringv through pipe 6%, which also may serve as a handle forthe device,.upon the housing, fills one or more chambers formed betweenthe valve and; the rotor 23 upon the said inside of the'housing; hemanner, in which the rotor is then actuated, may be best under-- stoodby sectioning away inFig. l the iront of the'housing together with theintakeportyand pipe 63, Bi l, whereupon we see, upon the, inside, thevalve 2i and rotor 23 in the very position, in which-the similarfvalve2| and rotor 3! shown inFig. 5L The'operation, of the device may fromthis point on be more readily followed in the View of Fig. 5. r

, The water entering through pipe 184 finds the vane 3 3 substantiallysquarely in its path, so that the stream of, water is divided, Part, ofit going up into a portion 13 of the spirally disposed groove formed bythe vane, in the toroidal annular groove 24, that portion 730i thegroove being however limited by the wing l5 formed betweenapair ofnotches 22 of the valve 2 i, so that the upper part of the stream ofwater is blocked in said portion'lfiiof the groove. The rest of thestream of the water passes from pipe M underneath the vane 31! intoanother portion '12 of the spirally disposed groove, said groove 12being limited atthetop by the wing 35, and at the bottom by the wing T6-of the valve 2!. Thus the stream of water entering by way of pipe 6% isblocked in the upper portion it of the housing. I

There is a third portion i l of the helically disposed groove, whichextends fromthe wing 16 to the bottom end of said groove, said thirdportion iii being however open to the outside by way of the port 28 ofthe rotor. Neither the valve 25 nor the toroidal part 24 of the groovesin the rotor can yield to the pressure exerted by the water in portionsE2 and 13. But the pressure, under which the water impinges upon the topof vane in the portion 53 of the groove has two components, one of whichis disposed in the and in the lower portion 12 of the helically disposedgroove extending in the rotor inside I tion I2 of the groove. But thistorque is several times exceeded by another force exerted in portion 12of the helically disposed groove by the water pressing down upon thesection of the vane disposed between portions 12 and 14. The rotativecomponent of this latter force is disposed in the same direction as theonly rotative torque we found acting in portion 13, and the rotor yieldsto these combined forces, counteracting moment the wing 15 of valve 2.!has slid in the journalled around its outer circumference.

cessecl sector 84.

helically disposed groove onto the port 28, so that the water occludedin portion '52 may now flow out of port 28, e. g. into theopen, and ontosponge 51'.

During further rotation of the rotor the portion 12 of the helicallydisposed grooveeventually assumes the position of portion is firstmentioned. The portion l3 has by that time assumed the po-sition'of theportion 72, and a new portion i3 is swung up; the water being divided bythe vane 35 into two streams flowing into new portions 13 an '52, sothat the hydraulic play starts over again from the starting point fromwhich on it was described, and the rotor-continues its rotation. 5

The large end of rotor 23 is rotatively supported at its center in thehousing, by way of ball hearing t! resting in the central hub 43. Butthis central supportas well as spokes id and ring 4%- may be avoided, sothat there is'a clear ,ath ior'the water leaving the rotor by way ofport 23, if the large end of therotor is This is illustrated in Fig. 5,where the rotor 35 is supported by the ball bearing 1'. in the bodyportion J8. of the housing. This ball bearing is developed for end aswell as for radial thrust, because it has to take up the reaction of thewater head built up by the rotor. acting as a pump in the vertical *pipel3 extending up from the elbow flange 38 said. body portion 13 extendingin this instance upon its outside in a straight conical formation,

whereas upon the inside thereof the conical portion 82 at the smallerend and the cylindrical portion 83 at the larger end are preserved inconformity with the outline of the rotor 35.

The outwardly conical body portion ":8 of the housing rests in acori'espondingl conically re- Said sector il i'is' made one with an openrectangular base 85 by way of a front wall 86 and inclined legs is!and'88 at opposite sides. But leg 88 is hollow, and corresponds inrespect to its interior arrangements to the extension -Iwhichaccommodates in Figs. 1 and 2 the valve 2!. In other words the leg 88accommodates the valve 2|, e. g. by way of a stud 53 in the manner shownin Fig. 2. The valve 2! again fits-into the body 82 of the housing byway of a slot 48; and there is again a tapped hub 63 admitting water tothe housing body 18 and connecting byway of a riser to a fluid supply,from whicha fluid is to be pumped up 'byway'of the pump of Figs. .5,G:and :-'7 into 'a pipe 19.

From the small end of rotor'ti ez-rtendsiashai-t 98 through the body 18of the housing-by-way of a stufling box 9 5. Shaft- 9D may-bedriven-from a suitable source of mechanical power; e. g. it may beconnected by 'couplingsz .to an electric motor $3 mountedupon.thezrectangularbase 85.

When the rotor is motor-driven as shown; the rotor is the driver and thevalve is the follower, as it is always the case in-connection with thefluid driven device of Figs. land 2., However, it is readilyunderstoodby those versed in the .art of helical gearing,'that underparticular circumstances, for instance when there is more than one vaneinvolvinga corresponding larger lead of the vane (Fig. 8) then'thedriving:mechanism may be applied to the valve .21, and the valve 21becomes the driver and rotor :31 the follower of the pump.

For-purposes of comparison the direction of rotation of the rotor, 65,and valve, 65; hasbeen assumed to be the same for the motor of Figs. 1and '2 as for'the pump of Figs. 5,6 and 7. Under these conditions thewater also fiows'the same direction through the devices; i. e. in amotor of Fig. 1 a fluid iszforced'in through port 62 and leaves, i, e.drainsbyway oftheport 28. -Whereas in the case of the pump of Figs. 5, 6and '7 the fluid is sucked in through port -62 (hub 63), and leaves byway of port 28 under pressure. Because the portions '13 and 12 of thehelically disposed groove of the rotor enlarge in the pump, when therotor is driven 'in the direction indicated by arrows 65,i. -e. inclockwise direction in Fig. 6. Thus a fluid'is sucked into the portions13 and 52 from the intake pipe 85!, until the vane 36 has moved past the'opening or port 62. Then no more fluid is taken into portion l2, butthe contents of said-portion are pushed out by'the wing 75 of valve 2!through port 28. Portion l2 eventually passes ithrough the stage atwhich portion'ld is shown the contents of portion l4 being pushed at thestage shown in Fig. 5 out through port "28 by the wing E6.

Thus the rotor SI of Fig.5 reacts 'in the direction of arrow 94,suchreaction'beingitaken'up by the'ball bearing 71. "The valve 2|'rea'cts up from the plane in which it is'in Fig.5, which reactionpresses it onto the edge 'Bl of opening 48, producing a better closingof thesu-c'tion compartments 72 and 73. These reactions :of the rotorand of the valve are respectively'opposite to the reactions of'these'parts in the motor of Figs. 1 and 2. But these reactionsofthe'pump of Fig. 5 are reversed, if the pump .is rotatedin an oppositedirection, and sucks in a fluid by way of pipe Hand discharges it"by wayof pipe 89. On the other hand the respective reactions in connectionwith a' motor like thatof Figs. 1 and 2 would also be reversed, if thepressure fluid were passed through the housing in an .oppositedirection; i. e. if the deviceofFig. 5 is used as a motor, and apressure fluid enters by way of pipe 19 and leaves by way of pipe 89,then the axial reaction of the rotor and of the valve are the same aswhen the device of Fig. '5 serves as a pump and the rotor is driven inthe direction of arrow 65.

A motor of Figs. 1 and 2 is-particularly useful, where the hazards ofan-electricarmotor are to be'avoided, or where thereis no supply ofelectricity, On the other hand motors-of-this kind compare veryfavorably with electrical motors in :respect to efliciency as well as inrespect to output/weight. The capacity "and pressure'performance-per-weight of apump like that shown :in Fig. 5 is alsoextraordinary.

When'the device'is executed in corrosion proof material, the driving ordriven fluid may be water, and the water may readily :be used forlubrication. Lubrication may be :provided for 111*.00111130131011 with.devices used with :gas by executing one 'or the other part, 'forinstance the zhousing, in -a self-lubricating material or metal. :Whileexperiments have shown, that devicesof ithis kind can be operated atvery high .speeds, 1 they are particularly useful in comparison withother motors in respect to low speed, because these motors can beoperated at a crawling speed; andthat is ordinarily impossible withelectrical motors.

:It'should be noticed, that the bottoms .of

:notches "22 .do not have to extend :into closing formation with the tip.or crown .of vane .30. However the .sealing of tthe various :parts uponeach other may be improved .upon1if awe curve the body :of the housingconcentrically to .the axis .of 'th'e'valveginwhich casethe bottom ofthe znotches illmay be in alignment with .the inner surface of the bodyof the housing, so

zthatthey also fit closelyontothe crown 101 :tip

of the vane 30. .Such arrangements will, for instance, be found in'themodified-devices-of Figs 8to 11.

.Aside from other-questions, in:particular manufacturing .and productionproblems, the lay- .out or partsmust also be-guided loy-considerationsof the structural strength of the parts.

.Thus the shape oinotches 22 in valve :2i and the center distancebetween the valve and'the =rotor must be'taken into consideration forproper sliding'of 'theparts upon each otheig a'nd more 0 particularlyconcerning the strength of the vane and the thickness of theslenderestportionla' of the column of-the rotor.- 'The shape of thehousing-affects, of course, the desired development'of the portions 72,?3 andi'l i of the spirally 'disposedgroove, and such developmentis-guided 'byconsiderations of 'thehature of the fluid'to -be used, efg.whether it is compressible like a gasgor isa non-compressible liquid,like water.

ceeding in a peripheral direction-meshes in rotation with one of thevanes of rotor H3, there being two such vanes, H4 and H5. Vanes H4 and II5 are entwined in double thread fashion.

Only a substantially symmetrical half is shown of the valve 'IIlQwhichportion is additionally cross-sectioned-and of the rotor H3, which ispartly cross-sectioned. In the end view of Fig. 9 the rotor and thevalve are not shown. This view shows, however, portions of one hose andof the lower ring I I5.

Ihe rotor I I3 rotatably fits the bottom portion 26 of the housing, andmay be suitably journalled and sealed in said portion by gasket rings H6at opposite ends. These rings are shown to have rims H8 which fitcorresponding recessesin the body portion of the housing. Aside fromthese recesses, and from the toroidal annular groove I I I the bodyportion 96 is shown to be cylindrical.

The rotor H3 has no ports, and a double flare iI'I extends clear throughrotor H3. This flare may serve, at either end of the rotor H3, to engageupon or to receive an object to be rotated pression I03 of said port,the fluid will rush into the one or two helically disposed groovesbetween vanes confronting the depression HO and will fill such grooveportions up to the valve I00 on the opposite side of the device. Thenthe fluid pressure will start rotating the rotor in the directionindicated by arrow I I9, i. e. in a counterclockwise direction seen fromthe top. In a manner corresponding to that described in connection withFig. 1, this rotation continues, the valve Hit rotating in the clockwisedirection indicated by arrow I253. The fluid will descend through therotating rotor and will leave'the device by the lower port, into whichin Fig. 8 the hose I58 is inserted.

Whereas in the modification just described in connection with Figs. 8and.9, the fluid enters'as well as leaves the device on one side,'afluid enters upon and leaves the modification of Figs. 10 and 11 in thedirection of the axis of'the rotor. The housing of this modification isshown exemplarily to have three consecutive steps I2I, I22 and I23. Thesmallest step I2I serves as a nipple, upon which is engaged the hose I24introducing the driving fluid, e. g.. the water. The rotor I24 occupiesthe two other steps I22 and I23, each one of which steps issubstantially cylindrical; however, there is a toroid'ally flaredinterconnecting portion'IZB between the steps I22 and I23, the pitchcircle of this toroidal section extending through the axis of valve discI21. A-ball bearing I28 is accommodated in the recess between steps IZIand I22, and another ball bearing I29 is retained uponthe free end ofthe body portion of the housing by a cap I39. Between these two ballbearings I28 and I29 the rotor I25 is journalled and has flared recessesI3I and I32 at opposite ends, the latter recess #32 being providedat itsentrance with means, e. g. an Edison thread I33, which removablyreceives a'suitable imple ment,e. g. a hollow brush end spray I34, inwhich perforations I35 are intersperse loctween bundles of bristle I35.

From the recess or countersink I32 extends the port I31 into thespirally disposedgroove of rotor I25, so that the fluidissues from themotor by way of said recess or countersink I32 out to the open or intoan attached implement, like brush I32. In this respect, as well as inrespect to other details of arrangement not specifically explained, therotor I25, and also the valve I21 meshing therewith, are substantiallyanalogous to the corresponding parts of the devices of Fig. 1 or 5.However, there is another intake port I33 upon the rotor, at its otherend, through which the fluid enters from the first step I2I, of thehousing, instead of entering from th sides, as it didin'Figs. 1 and 5,by way of the port 62. If this port I33 is made comparatively large, sothat a fiuid entering by way of step IZI of the housing strikessubstantially unobstructedly upon the upper extent of the topconvolutionof the vane I43 of the rotor I25, we may make good use of thekinetic energy of fluid entering by way of step I2I of the housing, inaddition to a posi jive conversion of the potential energy thereof,which latter proceeds in the manner explained in connection with theother devices hereinbefore described. The cap accommodating valve I2! ishere again made one with the body of the housing, the-cap beingrepresented by a lobe I39 extending radially froin the two steps 22 andI23, of the housing, and being covered by a closing lidIGIl. Exceptwhere there are clearances such as MI in the l0b'eI39, such clearancesreducing the friction of the valve I21 on said lobe, lobe I39 extendsfiat at it's'front M2, as a supporting surface for the valve I31; andsaid flat surface I42 extends right into the body of the housing, by wayof a slitsnugly but rotatably accommodating the valve'disc I21. A pinI43 removably arises from the flat surface'l iz and serves as a shaftfor valve I27. Pin I43 is retained in position by the lid I48, which isre-' cessed in order to clear the flat valve disc I27. But the lid abutsand closes upon the flat surface I42 by way of a rim I44 through" whichit is assembled with the lobe I39 by screw I45.

A flange I46 is screwed onto and closes upon an inclined ledge 'I IIbridging the two steps I22 and I23 of the housing and it extendsangularly from the lid I48.

A variety of implementsmay replace the brush I34, many of which, such asother rubbing implemerits, may use to advantage the driving iiuid,
